Lucy is sick, and Caro the betrayer has taken her and flown away--and it is up to Soli to track them down and find a cure for her best friend's illness.
Lucy and the old queen are sick and dying, and Kheelan and Caro take them to the Ladybirds in hopes of a cure, while Soli remains at the castle to deal with the Crows, but the Faerieground still has many secrets and there is treachery nearby.
The fate of Faerieground hangs in the balance--and Andria, mother of Lucy and Caro, is the key to whether the kingdoms will fall to the Crows, or be united in peace.
Soli is still in the kingdom of the Crows, who want to turn her into one of them--meanwhile the other six kingdoms are choosing whether to unite against the Crows, and Lucy has learned that her own mother, back in the world, could bring ruin if she crosses over to Faerieground.
As Lucy, Kheelan, and the united Faerie march to war against the Crows, Soli discovers who has been smuggling Kheelan's messages to her, and learns Caro's secret--and Lucy's mother returns to the Faerieground.
Lucy is back home in Mearston, fully recovered, but trying desperately to get back to Faerieground where her best friend Soli, Queen of the Faerie, is still a prisoner of the Crows.
